Antivirulence Potential Of Tr-700 And Clindamycin On Clinical Isolates Of Staphylococcus Aureus Producing Phenol-Soluble Modulins, Jason Yamaki, Timothy Synold, Annie Wong-Beringer

Pharmacy Faculty Articles and Research

Staphylococcus aureus strains (n = 50) causing complicated skin and skin structure infections produced various levels of phenol-soluble modulin alpha-type (PSMα) peptides; some produced more than twice that produced by the control strain (LAC USA300). TR-700 (oxazolidinone) and clindamycin strongly inhibited PSM production at one-half the MIC but exhibited weak to modest induction at one-fourth and one-eighth the MICs, primarily in low producers. Adequate dosing of these agents is emphasized to minimize the potential for paradoxical induction of virulence.

Dermoscopy: An Evidence-Based Approach For The Early Detection Of Melanoma, Angela Armstrong

UNF Graduate Theses and Dissertations

The purpose of this project was to evaluate the effectiveness of a practice-based dermoscopy training program for dermatology healthcare providers in order to improve their technique of performing clinical skin exams for the early detection of melanomas.

The overall incidence of melanoma continues to rise. More than 75% of all skin cancer deaths are from melanoma. Advanced melanoma spreads to lymph nodes and internal organs and can result in death. One American dies from melanoma almost every hour (American Cancer Society [ACS], 2009). Early diagnosis and excision are essential to reduce morbidity and to improve patient survival.

New Perspectives On Melanoma: The Role Of Pax3, Sandra Medic

Theses: Doctorates and Masters

Background: Cutaneous melanoma is an aggressive form of skin cancer, arising in cutaneous melanocytes. The transcription factor PAX3 is critical for the proper development of neural crest lineages including melanocytes. Melanocytic cells show continued PAX3 expression from melanoblast formation in the neural crest to their differentiation into melanocytes. While many studies clarify the importance of PAX3 in embryonic development of melanocytes, less well understood, and more perplexing, is the continued PAX3 expression in adult skin melanocytes. By contrast PAX3 is frequently found in melanomas and naevi, and its expression correlates with melanoma staging. In this study we explore the multiple …

Plasmacytoid Dendritic Cells Sense Skin Injury And Promote Wound Healing Through Type I Interferons, Josh D. Gregorio

Dissertations and Theses (Open Access)

Plasmacytoid dendritic cells (pDCs) are a rare population of circulating cells, which selectively express intracellular Toll-like receptors (TLR)-7 and TLR-9 and have the capacity to produce large amounts of type I IFNs (IFN-a/b) in response to viruses or host derived nucleic acid containing complexes. pDCs are normally absent in skin but accumulate in the skin of psoriasis patients where their chronic activation to produce IFN-a/b drives the disease formation. Whether pDCs and their activation to produce IFN-a/b play a functional role in healthy skin is unknown. Here we show that pDCs are rapidly and transiently recruited into healthy human and …

Solar Radiation Damage To Human Skin Mitochondria, Luciene Zanchetta

Doctoral

The central objective of this study was to assess solar radiation-induced changes in cellular function, mitochondrial function and mitochondrial DNA to further investigate the role of these energy-dedicated and metabolically essential organelles in the response to the main environmental stressor associated with skin cancer initiation. An in vitro approach was chosen employing the human malignant melanoma (A375) and human amelanotic melanoma (C32) cells and the human spontaneously immortalized keratinocytes (HaCaT). A Q-Sun Solar Simulator was used to expose cells to low-level simulated solar radiation (SSR) as it provides a mimic of solar radiation that is environmentally relevant in the UV …

The Relationship Between Obesity And Skin And Soft Tissue Infections, Juliana Swiney

MPA/MPP/MPFM Capstone Projects

The Problem:

It is well known that our country is experiencing an obesity epidemic: 33.9% of all adults are obese (BMI>30) and 67% of adults are either overweight or obese (BMI>25). Obesity is a risk factor for several serious disease states such as, diabetes, stroke, hypertension, heart disease and some types of cancer. It also has a less well defined relationship with skin and soft tissue infections.

Although it is known that excessive weight increases the opportunity for harmful skin conditions, this relationship has not been as well studied. Some of the mechanisms that predispose obese people to …
